3. INTRODUCTION
ADDICTION is a chronic disorder which is a combination of genetic ,biological and social factors
ex: gambling , alcohol consumption etc
Addiction avoider is based on simple principle of
controlling “ Brain waves”
KEY TERMS:
BRAIN
BRAIN WAVES
ADDICTION

4. BRAIN: ELECTROCHEMICAL ORGAN Temporal lobe produces brain waves
AMYGDALA controls
social sexual and other
emotions
Generates 10 watts of power

5. DIFFERENT BRAINWAVES AND ITS FREQUENCIES
SNO BRAIN WAVES FREQUENCY (HZ) ASSOCIATED WITH
DELTA Deep dreamless sleep
THETA Dreams
ALPHA Meditation
LOW BETA Active conversation
HIGH BETA stress, depression
Different brainwaves with their names and the situations when it occurs.

6. TYPES OF ADDICTION
PHYSICAL DEPENDENCY
PSYCHOLOGICAL DEPENDENCY
Appearance of charecteristic with drawal symptoms when drug is suddenly discontinued
Antideppresants
EX:cartisone,effexor
This chain can be stopped by doctor intervention
These are dependency of mind and lead to psychological withdrawal symptoms
These are opposite to physical dependency
EX:opium
This chain is difficult to break

7. RECOVERY THERAPY To assess the severity of problems of addiction
an index is developed known as ADDICTION SEVERITY INDEX based on
factors-:
Medical
Employment
Alcohol and other drug use
Legal
Family/social
Psychiatric
Medical detoxification,
Ibogaine, methadone-for healing opium addiction
Counseling classes

8. THE ADDICTION AVOIDER PRINCIPLE:
It works on principle of “BINAURAL BEATS”
“ A beating tone will be perceived
when two tones at slightly different frequencies
mixed naturally ,out of brain.”
Frequency of beating tones : Range hz Difference <30hz

10. WORKING
EEG SENSOR:
It Senses analog brain wave and applied to the 8515
microcontroller
0.7 inch diametre in size
It is a hard plastic outer disc made up of silver
Chloride cap

11. 8515 MICROCONTROLLER
PIN OUT DIAGRAM OFAT90S8515
“Utilizes the AVR® RISC Architecture”
118 Powerful Instructions
32 x 8 General Purpose Working Registers
Specifications:
Low-power, High-speed CMOS Process Technology
Fully Static Operation
Power Consumption at 4 MHz, 3V, 25°C
• Operating Voltages:
V (AT90S4414 and AT90S8515)
V (AT90S4414and AT90S8515)

12. AMPLIFIERS
GAIN FORMULA:
TOTAL GAIN = A1*A2*A3*A4
=2*10^5
A = -R2/R1,

13. OSCILLATORS & STEREO HEAD PHONES
WEIN BRIDGE oscillator generates audio freqs below 1500 hz
Two oscillators are designed with difference in frequency ranges
STEREO HEAD PHONES
It sends audio waves from two oscilators to the two
Sides of head phones

14. APPLICATIONS IT avoids the addiction caused by narcotic
Drugs and alchohol
Simple addictions like over-eating
Gambling etc
A person under deep depression
Can be cured
To study the resonance of brain
during brain diseases

15. FUTURE PROSPECTS MERITS: DEMERITS: Pregnant women Pace maker users
The concept of binaural waves can be further researched and
find out a communication with deaf and dumb people.
MERITS:
It is light in weight
Economical(costs around Rs3000/)
Head band completely touches skin
DEMERITS:
Pregnant women
Pace maker users

16. CONCLUSION References: www.nlm.nih.gov/medlineplus/
ADDICTION AVOIDER is the simplest and safest device used for prevention of addiction
